The form of the invention shown in Figures 1 and 2 of the drawings differs from that illustrated in my aforesaid pending application in that the collar used to secure the closure cap to a filling or dispensing neck is designed to be held by friction to the aforesaid neck. In the prior application, the securing collar is screw-threaded. In Figures 1 and 2, the reference character I designates a collapsible tube or similar container having a filling and dispensing neck 2 extending from the upper end thereof with its outer periphery shaped substantially as a frustrum of a cone. The closure member designated generally by the reference character 3 comprises an attaching collar 4 having a shouldered inner recess 5 shaped to t snugly on the neck 2 of the container I and to be secured thereto by tight friction fit.

The recess 5 has, at its upper end, a shoulder 5 adapted tov limit the movement of the cap on the neck 5. Ordinarily the recess 5 will be formed so that when it is securely applied to the neck 2 the shoulder 6 will be slightly spaced apart from the top of the neck 2.V The collar 4 is centrally apertured to provide an outlet for the contents of the container I, and the central aperture has a ring 'i secured therein by tight friction t. This ring 'I extends above the upper plane end 8 of the collar 4 to form a seat for a gasket 9 suitably secured in a recess I0 formedin a closure cap I I hinged to thecollar 4.

The hinge connection between the cap II and the collar 4 1s of a peculiar construction which permits the cap to be rotated from closing position on the collar 4 to an open inclined position in which the cap clears the dispensing aperture of the container both laterally and vertically. As shown in the drawings, the hinge connection comprises a pivot lug I2 extending laterallyvfrom the upper end of the securing collar 4. The plane of the upper face I3 of the pivot lug I2 is inclined with respect to the plane of the upper end 8 of the collar 4. This inclined plane face I3 forms a seat for a cooperating pivot lug I4 projecting laterally from the cap II. The face of the lug I4 contacting with the face I3 of the lug I2 is inclined at the same angle to the closing face I5 of the cap 3.

The pivot lugs I2 and I4 are centrally aperturtured to receive a pivot I6 which is preferably in the form of a rivet for securing the ycollar and cap permanently but rotatably connected to each other. The cap II insofar as its closing portion is concerned is of larger diameter than the outer diameter of the collar 4, thereby providing a. flange around the outer periphery of the collar 4 sothat the user may by merev pressure on the edge of the cap II move the cap from its closing position shown in Figure 2 to the open position shown in Figure 1.

VIt will be obvious from inspection of Figures 1 and 2 that the further the cap II is rotated anti-clockwise around its pivot I6, the greater will be its elevation above the plane face 8 of the collar 4. The angle of the pivot`lugs I2 and I4 is such that when the cap is rotated until its axis coincides with the axis of the securing collar 4, the gasket 9 will be pressed tightly down against the upper edge of the ring 'I, thereby insuring a close fitting airtight joint between the cap and the said ring.

The modification shown in Figures 3 to s is particularly adapted for permanent attachment to the filling neck of the radiators of automobiles and is designed so that the greater number of its parts can be stamped out of thin sheet metal. In Figures 3 to 8 the filling neck is designated by the reference character I'I; and, as usual in devices of this character, is provided at its upper end with an inwardly and downwardly turned annular flange I8. The closure proper, designed to be applied to the filling neck I'I, comprises a circular cap I9 having its outer circular edge shaped to form a depending iiange 29. The central part of the cap I9 is dished to form a cylindrical recess 2| in which is seated a gasket 22.

The recessed portion of the cap I9 is suitably apertured to receive the shanks of machine screws 23 and 24 which are threaded into bosses 25 and 26, respectively, projecting from the inner face of an ornamental cover 2'I which is shaped to project over and around the cap I9. The cover 2'I forms a suitable base for the ornament 28 such as'is in common use on radiator caps. This ornament and` base may, as is common in this art, be cast of any suitable material and in any desired ornamental form. Properly speaking, this ornamental cover and ornament form no part of the closure disclosed herein. However, because of the fact that the closure is constructed of very cheap stamped out material, it is highly desirable that provision be made for covering these cheap parts with some ornamental and protective cover.

The cap I9 is secured to the radiator neck I1 by means of a thimble 29 having an annular flange 30 extending outwardly from its upper end. The thimble 29 fits snugly within the flange I8 of the radiator neck I-'I, and at its lower end is provided with outwardly turned locking lugs 3l and 32 adapted to slide through slots 33 and 34, respectively, formed in the flange I8 of the neck II. These lugs and slots constitute a sort of bayonet joint between the thimble 29 and radiator neck I'I.

. When the thimble 29 is properly secured to the radiator neck, the flange 30 serves to clamp a pivot collar 35 securely to the radiator neck I'I, an annular gasket 36 being interposed between said collar and the top of the radiator neck to ensure an airtight joint. T o facilitate separation or assembly of the thimble 29 and the radiator neck I1, the lower end of the thimble is provided with inwardly directed lugs 3'I and 38 adapted to receive a special tool for the purpose of effecting rotation of the thimble to move its locking lugs 3I and 32 into or out of registration with the slots 33 and 34.

Y 'I'he pivot collar 35 is provided with diametrically opposite recesses 39 and 49 to permit the lugs 3l and 32 to pass therethrough-when the collar 35 is being assembled on the thimble 29. The collar 35 has formed integral therewith a radially projecting extension 4I stamped to form a recess or casing 42 having a wall 43 inclined with respect to the plane upper face of the aforesaid collar. The center of the inclined wall 43 is suitably apertured to receive a shank 44 of a headed pivot connecting the cap I9 pivotally to the collar 35. Ihe cap I9 is stamped to form a wall 45 inclined at the same angle to the plane face of the cap I9 as the wall 43 is inclined to the plane face of the collar 35.

A gasket 46 is interposed between the walls 43 and 45 to permit the yieldingmovement necessary to insure an airtight fit between the gasket 22 in said cap and the flange 3l) of the thimble 29. vWhile Figure '7 ofthe drawings shows a rivet rto the upper plane face of the flange 52.

as the pivot connection betweenn the cap |9 and the collar 35, the invention must not be Vconsidered as limited in any way to any particular form of pivot connection. To insure a proper yielding t between the Walls 4-3 and 45 and the gasket 46, a cup-shaped spring washer 41 is interposed between one head of the pivot 44 and the upper face of the inclined wall 45. 'Ilo prevent rotation of the cup-shaped; spring washer 41, the said washer is provided with a small lug 48 projecting radially into an aperture 49 formed in a wall 50 connecting the inclined. wall 45 to the plane face of the cap I9.

The operation of this form of the invention is quite similar to that illustrated in Figures l and 2 of the drawings. The structural differences, however, are such as are inherent in a device of this character which is stamped from thin sheet metal so that it can be manufactured in great quantities very cheaply to adapt it for use generally on lling or dispensing necks such as the necks of automobile radiators.

'I'he form of the invention shown in Figures 9 to 15 differs mainly from that shown in the preceding figures in that the thimble and cap connected thereto are die-cast instead of being stamped out of thin sheet metal. In this form, the thimble is cast to provide a pivot collar 52 projecting laterally from the upper end thereof and is also constructed to form the radial locking lugs 53 and 54 adapted to slide in the slots 33 and 34 formed in the flange I8 of the filler neck |1. A gasket 36 is interposed between the lower face of the flange 52 and the upper end of the filler neck |1. The thimble 5| is provided at its upper end with an annular projection 55 forming a seat for the gasket 56 which is suitably secured in a recess 51 formed in the die-cast cap 58. Any suitable ornamental cover 59 may be secured to the cap 58.

The flange 52 corresponds to the pivot collar 35 of the form of the invention illustrated in Figure 4 of the drawings. This flange 52 is provided with a recess 68, one wall 6| of which is inclined 'I'he cap 58 is provided with a projection 62 having a plane face 63 inclined at the same angle to the lower plane face of the cap 58 as the wall 0| is inclined in the flange or collar 52. The inclined portions of the flange 52 and the cap 58 are provided with registering apertures to receive the shank 64 of a headed pivot 65, a cupshaped spring washer 66 being interposed between one head of the pivot and the upper inclined face of the projection 62 to permit vertical separation of the cap 58 from the collar 52 whenever the cap is rotated from closed to open position. The operation of this form of the invention is quite similar to that of the form shown in Figures 3 to 7 and will be evident to persons skilled in the art without further description.

The form of the invention illustrated in Figures 16 to 22 of the drawings is particularly adapted for production cheaply and in large quantities. This form of the invention is a stamped sheet metal product primarily intended as a closure for the gasoline tanks of automobiles.

In this form of the invention, a thimble` 51, having a flange 68 formed at its upper end, is seated on a filler neck 69 which may be that of a gasoline tank or automobile radiator. The neck 69 is inwardly and downwardly turned at its upper end to provide a flange which forms a collar for the thimble 61 when the latter is positioned therein. The flange 10 is provided at diametrically opposite ends with slots 1| and 12 designed to permit the sliding movement therethrough of the lugs 13 and 14 which are outwardly turned at diametrically opposite points of the thimble 61 to form with said slots a locking bayonet joint connection for the thimble and Iiller neck 69.

The cap is depressed at its center to form an annular recess 16 in which is seated an annular gasket 11 adapted to form an airtight joint with the pivot collar or flange 68 of the thimble 61. An ornamental shell 18 may be secured frictionally or otherwise to the cap 15 which is provided with a series of protuberances 19 spaced around the cap 15 to form a rest or support for the shell 18.

The flange or collar 68 is stamped to form a recess 80 having a Wall 8| inclined to the plane face of the flange 68. The cap 15 is stamped tol form a recess 82 corresponding in the inclination of its wall 83 relative to its plane face with the inclination of the wall 8| of the flange 68 to the plane face thereof.

A metal washer 84 is interposed between the inclined walls 8| and 83 to eliminate wear and to secure perfect performance, and surrounds a pivot 85 passing through registering apertures in the walls 8| and 83. A spring cup washer 86 of the same type as that disclosed in Figure '1 of the drawings is interposed between the head of the pivot 85 and the upper face of the inclined wall 83; and a radial extension 81 projects from the lower edge of the washer 86 into an aperture 88 formed in the wall connecting the inclined wall 83 to the plane face of the cap` 15. The operation of this form of the invention is quite similar to that of the forms'previously described. The main difference between this form and others residing in the structure and arrangement of parts to adapt it for manufacture in great quantities at very low cost.

'I'he form of the invention illustrated in Figures 23 to 27, inclusive, is particularly adapted for die-cast production. 'Ihis form comprises a collar 89 having an annular recess 90 adapted to t frictionally over the upper end of a standard ller pipe 9|. A shoulder 92 of the said recess forms a stop to contact with 'the top of the filler pipe 9|. The collar 89 is provided with the laterally extending lug 93, which in the casting of the collar, is constructed to form a wall 94 having a pivot aperture 95 formed therein. The wall 94 is inclined so that the axis of the aperture 95 is also inclined to the upper plane face 96 of the said collar.

The cap 91, in this form of the invention, is of greater diameter than the collar 89 and is provided with a radially projecting lug 98 having a wall 99 inclined to the plane of the lower face of the cap at the same angle as the plane of the lug 94 is inclined to the upper plane face of the collar 96. The lug 98 has an aperture |00 extending therethrough and adapted to register with the aperture 95 in the projecting lug 94 of the collar 89. A headed pivot |0| extends through these registering apertures and the lower end thereof projects sufficiently below the lower face of the lug 93 to permit the use of a spring cup washer |02. The cap 91 is provided at its center with a circular nub |03 adapted to t snugly into the central aperture |04 of the collar 89. In this form of the invention the nub |03 gives the proper clicking eifect when it is moved into or out of closing position. Air vents |05, |06 and |01 are formed by providing recesses extending radially across the upper edge of the collar 89.

In the form of the invention illustrated in Figures 28 to 31, the cap is adapted to be formed as a stamped sheet metal product. This form includes a collar |08 adapted to be secured on a cylindrical filler neck |09 by friction fit. The upper end of the collar |08 is extended inwardly to form an annular flange IIO which is provided at various parts with downwardly projecting lugs I I I adapted to seat on the upper end of the lling neck |09. Directly above the projections III the ange II 0 is provided with radially extending Ventilating notches or grooves II2.

The collar I 08 is stamped out to form the pivot receiving lug I I3 arranged at an angle to the upper plane face of the iiange IIO. The cap II4 is somewhat larger in diameter than the collar |08 and is stamped to provide a pivot lug II5 arranged at the same angle to the plane face of the cap as the pivot lug I I3 is arranged with respect to the upper plane face -of the ange II 0. A headed pivot IIS extends through registering apertures in the lugs II3 and II5 to connect the cap pivotally to the collar I08. The locking ef fect between the cap and collar is secured by providing the upper face of the collar |08 with a nub I II adapted to seat in a corresponding recess II8 formed in the cap IM. In this form of the invention, the natural resilience of the several parts being depended upon to make the necessary closure Contact between the collar and its cap. The operation of this modication is substantially the same as that of the other forms of the invention.

It will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of my invention, or sacrificing any of the material advantages thereof; and I reserve the right to make all such changes as fairly fall within the scope of the annexed claims.
